RADIATOR CONSTRUCTION.

Application filed February 28, 1921.

To all whom it may concern:

Be it known that I, BURLING T1. Rooms, a citizen of the United States,residing at Baltimore. in the State of Maryland, have invented certainnew and useful Improvements in Radiator Constructions; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to radiator construction.

Among the objects of my invention are To provide a radiator having largecooling surfaces which are provided without the use of a large amount ofmaterial.

To provide a radiator having the parts so constructed and arranged thatthe water to be cooled must follow a tortuous path and be entrained insuitable pockets at various locations during its passage through theradiator in order to provide a maximum of time for the radiation of theheat from the water.

To provide a radiator having but small resistance to the passagetherethrough of the cooling medium.

In carrying out my invention I make use of the instrumentalitiesillustrated in the accompanying drawing, in which:

Figure 1 is a partial front view of aradiator constructed according tomy invention and suitable for use on an automobile.

Fig. 2 is a perspective view of the tube used in the construction of myimproved radiator.

Fig. 3 is a perspective view of a portion of one of the strips used inthe construction of my improved radiator.

Fig. 4C is a central section through one of the elements of my improvedradiator shown in Fig. 1, the section being taken in a plane parallelwith the face of the drawing.

In the drawings: 7

5 represents the top header and .6 the bottom header of the radiator.These headers are each shaped as usual in the form of a hollow metallicbox, the upper header 5 being provided as is usual with a pipe for theinflux of water or other cooling medium thereto, and the lower headerbeing provided Specification of Letters Patent.

Serial No. 448,351.

with a similar pipe for the ettlux of said medium therefrom. Neither ofthese pipes are illustrated. I

The bottom of the header 5 is provided with a plurality of spaced slotssuch as T and the top of the header 6 is provided with a plurality ofspaced slots such as 8, the slots 7 and 8 being in alignment.

Each element of my improved radiator is composed of strips such as 9 and10. These strips are each provided with a plurality of flat portionssuch as 11 alternating with a plurality of crimped portions 12. The tube13 has the cylindrical body 14 and the ends 1515 swedged to fit withinthe crimped portions 12 when the latter are assembled together as shownin Fig. 1. The flat portions 11-11 of oppositely disposed elements aresoldered together and the crimped portions 12-12 are soldered to theends 15 of the tube 13. The ends 15-15 of the tube 13 are made of suchlengths parallel to the axis of said tube that the inner edges of saidends will extend inwardly to about the ends of the crimped portions 16,which crimped portions are in substantial alignment with the flatportions 11-11.

The crimped portions 1616 are provided in order to provide an openingfor the cooling medium to circulate and also in order to provide pocketsin which the speed of the cooling medium will be slightly reduced andthereby provide more time for the radiation of heat therefrom.

The strips 9 and 10 are each provided with bent ends such as 17 and thelatter are soldered to the headers 5 and 6 so that the end crimpedportions 16 will be in substantial alignment with the slots 7 and 8.

Thus it will be seen that I provide a simple, cheap and effectiveradiator having but few parts.

While I have shown but one embodiment and application of my invention,yet it is to be understood that many changes may be made therein withoutdeparting from the spirit thereof.

The air circulates through the interior of the tube 13 and between thecrimped portions 12 and 16 of adjacent elements.

I claim An element for a radiator comprising a pair of oppositelydisposed strips, each strip having a plurality of fiat portionsalternating with a plurality of crimped portions, orimped portionsbetween said first named crimped portions and extending between saidflat portions, and a. tube mounted between said first-named crimpedportions having ends to fit said first-named crimped portions, said flatportions being soldered together at their ends and the ends of said 10first named tube being soldered to said t-riniped portions.

In testimony whereof, I aflix my signature.
